Beware of dishonest sellers who provide fake 4G or 5G Machine just make a built in Jammer inside only and they also promise a much faster sending speed and radius, but in reality they are just doing fake count in there.
 
Machines with approximately same size are impossible to get a larger radius and speed. Hitech is a leader of this field are using the best hardware and the latest software for this field. 
So we can guarantee that our products can reach the maximum achievable speed and radius in real data.
